Engine mounting

Okay, I have a problem I have not read about before and need some help. Must admit on this one I am a little embarrassed to ask.

My car is at the body shop for panel fitting and bodywork. Engine in the car but without intake and carbs. The bonnet fits nicely on the car. I am going to use HD8 carbs on my BT7 and folks who have done that before have told me I need to cut away a little of the diagonal brace that runs from the firewall to the frame so as to avoid the bottom of the rear carb hitting the brace. Makes sense, since on BJ8s the diagonal does have a factory modification to do just the same thing.

Well, when I fit the intake manifold and carbs I discovered that my engine is sitting up too high in the engine compartment! If I put a straight edge across the shroud where the oil cap is on the rocker cover I have about 1/2" from the center of the cap to the botom of the straight edge, when I believe that measurement should be at least 1 1/4." So my engine is about 3/4" to high causing the top of the dashpot to hit the inside of the bonnet and there is no way I could install the front air cleaner.

I am using new rubber pads on my original engine mounts, but for the life of me I cannot figure out why the engine is sitting high. I am using a Smitty-Toyota gearbox and at first I thought that perhaps the bracket was tilting the motor to the rear, but I rejected that notion because there are so many folks out there with the same conversion and I have never heard anyone mention this as a problem.

Is it possible to install the mounts incorrectly? Is there an adjustment in the mounts that I am not seeing? I think the mounts are the same for all 6 cylinder cars.

Any thoughts would be appreciated. I am stumped, but I am also confident that I must just be missing something silly. Help!

Hi Lin,
Well, at first glance it looks like your motor mounts may be misadjusted. See dimension ā€œAā€ I think your mount is on the left in the diagram.

Hi Lin, I think if you install the large rubber blocks the wrong way around you can end up that way. The picture labeled "The early type " is identical to a BJ8 Mount??---Keoke?
 
Greg and Keoke,
Thanks to you both. I will explore the mount assembly issue when I pull the motor. Does anyone sell the shims? They ar NA in the Moss catalog. I didn't have any shims on my car when I disassembled it.

Lin, These would be an easy part to make or to have made if you know someone with some sheetmetal tools. Let me know and I can post pictures/dimensions for you.

Cheers,
John
 
Hi Lin, Don't worry about the shims mount that Mill as solid as you can get it.--Fwiw---Keoke- /ubbthreads/images/graemlins/hammer.gif
 
I had the same problem with my 1960 BN-7. The new motor mounts had the motor to high in the engine bay. The thing showed the correct distanct between the upper and lower mount, strange. I had to remove the main large rubber blocks and rotate them 180, This solved the problem. One last thing, I also had to remove the dowel pin that now was 180 from the hole in the mount steel. Must have been made in China, but that worked. /ubbthreads/images/graemlins/yesnod.gif
 
guys,tell me have i evolved into the relm of terminal dislexea,or would it not be necessary for him to remove the shims not add them in order to lower the engine,or rotate the blocks 180 deg.? /ubbthreads/images/graemlins/crazyeyes.gif
 
Hey 7777, you playin parrot or sumpin we alredy told him what to do. /ubbthreads/images/graemlins/hammer.gif--Keoke

Hi Anthony,

The shims only move the top rubber buffer .. not the engine mount and are used to set the gap between the two pieces.

John
 
keoke,not at all,but then why he askin were to buy/make shims? i surprized ya just didnt tell him to (your favorite thing) "cut" the mounts in half! /ubbthreads/images/graemlins/crazyeyes.gif
